The study was undertaken at Dumki upazila covering an area of 92.41square kilometer with 5 unions and 24 villages in Patuakhali district, Bangladesh. This upazila is very important for aquaculture farming due to favorable resources and climatic conditions.Primary data were gathered by field surveys in terms of fish culture, feeding, fertilization, production including constraints and data for production cost and profitability were collected over a 6-months period, from May to October 2013. A combination of the following participatory, qualitative and quantitative methods was used for primary data collection.
Participatory rural appraisal (PRA)
For this study, the PRA tool focus group discussion (FGD) was conducted with the fishermen including women and children. Focus group discussion was used to obtain an overview of fishing, utilization of gear and craft, fishing season, availability of fish, marketing system, fishing problem, income source, main profession and fishermen’s livelihood. A total of 12 FGD sessions were conducted where each group size was 5-7 persons (total 75 fishermen) and the duration of each session was approximately 2h. Focus group discussion sessions were held in river side tree shades and in front of village shops wherever there were spontaneous gatherings and where participants could sit, feel comfortable and were easily observed.
Questionnaire interviews
For questionnaire interviews, household farmers were selected through simple random sampling. A total of 1170 farmers, day labourers, drivers, fish farmers, businessmen, NGO workers, and teachers’ household data were collected. Questionnaire interviews were focused on fish culture, feeding and fertilization, productivity, culture system, culture constraints, production costs, return and profitability, marketing process, agricultural crop production, poultry farms, daily income and life of the farmers.
